Nope. The tilt is supplied by hydraulic actuators rather than by
gravity so you'd simply steer into a turn the same way you would in a
cage, rather than steer to the *outside* of a turn (counter-steering)
to cause the vehicle to bank to the inside and begin the turn.
Neither would it track around a turn like a motorcycle because the
rear tires don't lean towards the inside of the corner: they remain
upright.

Disregarding that:
A) There is a tiny LNG infrastructure issue that needs to be resolved.
B) OSAHA is going to have to come to grips with major accidents while
the hillbillies figure out that smoking near volatile gases is
honestly bad for their health.
C) A market full of employed persons is always nice though unlikely to
find in our US of Dependency...
